Title: Improvements in devices for curling or straightening hair or animal furs
IPC: C14B1/24
Filed: 1930-11-03
Abstract: 366,532. Hair - curling appliances; screw and nut gearing. BODA, J., 3, Szentkiralyi U., Budapest. Nov. 3, 1930, No. 33038. [Class 131.] A device for curling or straightening hair or fur comprises an electrically-heated member coacting with a shield and adapted to be rotated or oscillated as desired by a motor drive. The heated member 1 is rotatably mounted in a bearing 24 in the handle 4 to which is pivoted a shield 2 carried by a handle 3. The member 1 contains heating resistances 22, 22<1> supplied with current through slip rings 19, 20, brushes 17, 18 and wires 71, 8<1>. The member 1 is driven from the motor through a flexible shaft or cable 9, a clutch 28, 28<1>, grooved cylinders 30<1>, 30 which coact with a sleeve 33, and a clutch 48<1>, 48, the shaft 45 of .the clutch member 48 being connected to the member 1 by a sleeve 46. The clutch members 48<1>, 48 are normally held in engagement by a spring 49 but are released, should the pressure of the shield 2 on the hair be excessive, by a bell-crank lever 50, 51, actuated by an adjustable dog 54 on the handle 3. The cylinders 30<1>, 30 are slightly movable relatively in a longitudinal direction and are connected respectively to the shaft 29 of the clutch member 281, and the shaft 31 of the clutch member 48<1>. The cylinder 30<1> is provided with a pin 35 engaging in a recess 36 in the cylinder 30, which recess contains a ball 37. The sleeve 33 is provided with pins 34, 341 engaging respectively in helical grooves 32, 321 in the cylinders 30, 301, the groove 32<1> being endless. The sleeve 33 is provided also with a slot 41 adapted to be engaged by a hook 40 on a slide 39 when the slide is in the advanced position, the hook being disengaged from the slot, when the slide is retracted, by the cooperation of a cam surface 42 on the hook with the edge of a slot 43 in the casing. In operation, the tress of hair to be treated is clamped between the member 1 and the shield 2 and, if the member 1 is to be rotated, the hook 40 is disengaged from the slot 41. When the cylinder 30<1> is rotated by the shaft 9, the sleeve 33 owing to the resistance to rotation of the cylinder 30, is rotated a little relatively to the cylinder 30, thus pressing the cylinders 30, 30<1> together until the pin 35 binds against the ball 37, when the cylinders and sleeve rotate as a unit. When the member 1 is to be oscillated, the slide 39 is advanced so that the hook 40 engages the slot 41, thus holding the sleeve 33 against rotation. Rotation of the sleeve 30<1> then causes the sleeve 33 to reciprocate longitudinally, which reciprocation effects rotary oscillation of the cylinder 30 and member 1.

Patent GB-522627-A (GB)
Title: Improvements in or relating to control apparatus for prime movers
IPC: H02J3/42
Filed: 1938-11-16
Abstract: 522,627. Governors. ASSOCIATED BRITISH. ENGINEERING, Ltd., (formerly PETTERS, Ltd.), and GARTH, H. Nov. 16, 1938, No.33268. [Class 57 ] A device for controlling a prime mover such as a Diesel or other internal combustion engine adapted to be coupled to alternate electric generators forming part of electric generating installations is constructed with a centrifugal governor which controls the engines when under full load and when under light load and hand control overrides the automatic control and permits the generator to be driven synchronously with rest of the plant before being put to full load. When the governor acts, increase of speed causes a shaft 13 to rise and a thrust bearing 14 rotates a shaft 16 clockwise and a lever 17 on this shaft by means of adjustable link mechanism 18, 18a, 18c draws a rod 12 to the right, and by spring connections 12b acts on valve rods 11a of fuel pumps 11 which supply the Diesel engines, and thus reduces the supply of fuel. An adjustable spring 12 permits the action of the governor to be regulated, and when hand-control is desired a shaft 23 is rotated causing a cam 22 to move the rod 12 out of the range of action of the governor. Angular adjustment of the cam 22 then effects a fine adjustment of the rod 12 and thus of the supply to the fuel pumps. In its inactive position, shown by dotted lines, the cam 22 limits the maximum supply of fuel to the fuel pumps 11. The fuel supply can be cut off by moving the shaft 16 by means of a hand-lever 25, Fig. 2, and this lever may be held in the stop position by a lever 29 which operates an air valve 31 for starting the engines when it is moved counterclockwise to release the lever 25. In a modifiation the cam 22 may be displaceable axially into and out of contact with the rod 12. In a further modification, Fig. 6, the control is effected by a single lever fitted on a cam shaft 28 having a cam 37 having three levels 37a, 37b, 37c. In the position shown the surface 37b controls a lever 38 on the shaft 16, but the governor 10 can operate to control the speed On further clockwise movements of the shaft 28 the hand control is first brought into position, and then the stop position is reached. The start is effected by moving the shaft in a counterclockwise direction, when the cam 30 operates the air valve 31. The overriding control mechanism may act on a separate fuel control device not controlled by the governor, e.g. on a ported sleeve in the pump cylinder. Specifications 173,769, 240,587, [both in Class 7.(vi)], and 241,646, [Class 57], are referred to

Title: Method and apparatus for reducing tubular blanks
IPC: B21B21/00
Filed: 1937-12-02
Abstract: 493,405. Rolling tubes. KRAUSE, F. R. Dec. 2, 1937, No. 33405. Convention date, Dec. 2, 1936. [Class 83 (iv)] A tube 26 on a mandrel 24 is reduced, hot or cold, by one or two pairs of grooved rolls 14 and 18 which are rolled along and pressed on the tube by hardened shaped platens 7, 8, mounted in a housing 1 reciprocated by a crank disc 5, the tube being freed from roll pressure on the return stroke so that it can be given an increment of feed along the fixed mandrel. A hydraulic piston-rod 33 fixed on the roll housings 9 cause the roll to lag behind the return of the platens, so freeing the rolls from pressure after which fluid pressure is reversed to the right end of the cylinder 32, to bring the roll surfaces in contact with the platens for the next working stroke. The housings of each pair of rolls are held together by a spring 36 to allow relative movement. A fluid pressure tube clamp 69 is actuated, e.g. from the reciprocated housing 1 to hold the tube during working and to unclamp it for an increment of feed by a hydraulic cylinder 56 that pushes along the carriage 51 of the chuck 54 so moving the tube along until the carriage comes against a stop 58. This stop has been travelling along its screw 61 during the working and return strokes, the screw being rotated by belt 62, variable speed drive 63, and shaft 64 coupled, e.g. to the main shaft. At intervals the mandrel is pulled back through the tube by hydraulic cylinder 99 which also serves to strip the mandrel from the finished tube. The chuck 54 and tube and mandrel is rotated step-by-step during the release of the clamp 69, through gears 71, 72, shafts 73 and 74 by ratchet pawl 79, Fig. 6, the housing 81 of which is oscillated by a connecting rod 84 moved up and down by lever 86 by a cam 87 driven by a chain wheel from the main drive shaft 64. A safety device is provided by the stronger spring 98 which in case of jamming is depressed instead of the spring 94. When the chuck 54 has travelled as far as the clamp 69, it may be released and backed off and reclamped further back on the tube or on mandrel rod itself. The pointed mandrel gives a thicker and stronger end to the tube so preventing splitting. Alternatively, the carriage 1 may be stationary and the tube may be reciprocated through the mill. If three pairs of rolls are used, the tube turning mechanism may be omitted. The roll necks of each pair are geared together to maintain accurate registering. The rolls 14 have outwardlyflaring grooves to allow spread of the tube during reduction while the rolls 18 have semicircular grooves to finish the tube surface.

Abstract: 1,033,133. Transistor circuits. STONE-CHANCE Ltd. Nov. 7, 1963 [Sept. 3, 1962], No. 33744/62. Heading H3T. [Also in Division G4] A pulse producing circuit for a marine flashing light equipment, Fig. 1 (not shown), comprises a SCR switch 3 which is switched on by pulses from generator 4, and switched off by pulses from generator 5, each generator comprising a pair of complementary transistors. The generator 4 is gated on and off to give groups of pulses by the output from a counter 7 controlled by group generator 6. Generators 4, 6 may be switched by a transducer 8, e.g. a light-sensitive transistor. Generator circuits.-The generators of units 4, 5, 6 each comprises a pair of normally non - conducting complementary transistors T2, T3, Fig. 2. As capacitor Cl charges from reference voltage RV the base potential of T2 reaches a point where both transistors switch on, producing an output pulse. Transistor T4 then conducts, discharging capacitor Cl which switches off transistors T2, T3 and the cycle recommences. In order to obtain a stable value, the voltage LRV may be obtained from a chain of semi-conductor diodes, Fig. 3 (not shown). Group counter, Fig. 5, comprises a bi-stable circuit comprising complementary transistors T5, T6 and a counting chain of SCR's CR1 ... CRn. A pulse from generator 6 switches on transistors T5, T6, providing the reference voltage RV to generator 4 which starts to operate. At the same time SCR CR1 is switched on priming CR2 which is switched on by the next pulse from generator 5. Subsequent pulses from generator 5 switch the conductive state down the counting chain until CRn conducts, providing an output pulse which switches off transistors T5, T6, thus removing the voltage RV from generator 4. The reference voltages to units 4, 6 may also be controlled by a lightsensitive transistor, Fig. 6 (not shown). SCR switch, Fig. 4, comprises a pair of silicon controlled-rectifiers SCR1, SCR2. Application of a pulse from generator 4 switches on SCR1 to connect the loads to the supply and application of a pulse from the unit 5 switches on SCR2, thus switching off SCR1. The load resistor LR5 of SCR2 is made large enough for SCR2 to extinguish at the termination of the pulse from unit 5. Alternatively a second load (load 2) may be included.
